Cross-sectional data were analyzed for a possible relationship between household densities and physiologic alteration, based on socialization experiences with siblings in an earlier home environment. The measure of household density was persons-per-room and the measure of physiologic alteration was urinary vanillylmandelic acid. The results show an interaction between number-of-sibs and number-of-younger-sibs, with a statistically significant positive correlation between household densities and VMA values for subjects with fewer total sibs and no younger sibs, while a negative correlation was observed for subjects with one or more younger sibs. One possible interpretation of these results is that the physiologic response to crowding in humans is dependent at least in part on the earlier socialization experiences of the individual.
基于早期家庭环境中与兄弟姐妹的社交经历，对横断面数据进行了分析，以探讨家庭密度与生理变化之间可能存在的关系。家庭密度的衡量指标是人均房间数，生理变化的衡量指标是尿香草扁桃酸。结果显示，兄弟姐妹数量与弟弟妹妹数量之间存在相互作用，对于总兄弟姐妹较少且没有弟弟妹妹的受试者，家庭密度与香草扁桃酸值之间存在统计学上显著的正相关，而对于有一个或多个弟弟妹妹的受试者，则观察到负相关。这些结果的一种可能解释是，人类对拥挤的生理反应至少部分取决于个体早期的社交经历。
